A lot of good stuff, reading C++ errors is like learning an extra language on top of the C++ language, I can't wait to try it out.

> How do I get at some private field?

That one is interesting! I wonder how smart it is.

For instance in the following example:

    class foo
    {
    public:
      std::pair<int, int> get_coordinates() const { return std::make_pair(m_x, m_y); }
    
    private:
      int m_x;
	  int m_y;
    };
    
    
    void test(foo *ptr)
    {
      if (ptr->m_x >= 3)
        ;// etc
    }

I wonder if the compiler would be able to figure out that m_x is accessible via `ptr->get_coordinates().first` ?
